	* sem_attr.adb (Check_Dereference): When the prefix of a 'Tag

	a classwide type (for which Is_Object_Reference holds), but it can
	also be a value conversion for an access-to-classwide type. In the
	latter case, there is an implicit dereference, and the original node
	for the prefix does not verify Is_Object_Reference.

	(truly_local_externals, first_builtin_decl, last_builtin_decl)
	(make_scope, pop_scope, in_parm_level_p, set_block)
	(any_external_decl, record_external_decl, bind_label, getdecls)
	(link_hash_hash, link_hash_eq, merge_translation_unit_decls)
	(c_reset_state): Delete.

	(I_TAG_DECL, I_LABEL_BINDING, I_LABEL_DECL, file_scope)
	(external_scope, binding_freelist, bind, free_binding_and_advance)
	(push_file_scope, pop_file_scope): New.

	(mark_forward_parm_decls, build_compound_literal)
	(grokdeclarator, start_function, check_for_loop_decls)
	(identifier_global_value, record_builtin_type): Minor adjustments
	for new bindings structures.  Improve diagnostics and commentary.
	* c-objc-common.c (start_cdtor, finish_cdtor): Adjust calls to
	pushlevel/poplevel respectively.
	(c_objc_common_finish_file): Don't call merge_translation_unit_decls.
	* c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
	Warn about YYDEBUG not being defined only if -dy.  Remove no-longer-
	correct loop over multiple translation units; call fatal_error if
	requested to compile more than one file at once.  (This disables
	IMA temporarily - an up-front error being preferable to a crash.)
	* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
	(all actions): Adjust calls to pushlevel/poplevel.
	(parsing_iso_function_signature): Delete.
	(extdef_1): Fold into extdef.
	(old_style_parm_decls_1): Fold into old_style_parm_decls.  Don't
	warn here about function definitions in the wrong style.
	(after_tyle_declarator, parm_declarator_starttypename)
	(parm_declarator_nostarttypename, notype_declarator): Remove
	commented-out productions.
	(parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
	an empty TREE_LIST node.  Adjust calls to get_parm_info.
	(parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
	to suppress -Wold-style-definition after this error.
	(c_parse_file): Don't clear the binding stack or call
	finish_fname_decls here.  Correct comment.
	* c-typeck.c (same_translation_unit_p): Export.
	(common_type): Use c_override_global_bindings_to_false, not
	pushlevel/poplevel/declare_parm_level.
	* c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
	LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
	and LANG_HOOKS_GETDECLS with do-nothing stubs.
	* objc/objc-lang.c: Likewise.
	* objc/objc-act.c: Adjust all calls to pushlevel, poplevel,
	get_parm_info.
	(OBJC_VOID_AT_END): Delete; replace all uses
	with void_list_node.
	(generate_forward_declaration_to_string_table): Delete.
	* objc/objc-act.h (OCTI_STRG_DECL, UOBJC_STRINGS_decl): Delete.

	* coverage.c (create_coverage): Don't pushdecl anything.
	* langhooks.c (lhd_clear_binding_stack): Call
	lang_hooks.decls.poplevel, not poplevel.
	* tree.c (list_length): If ENABLE_TREE_CHECKING, abort on a
	circular list rather than going into an infinite loop.

cp:
	* cp-lang.c (c_reset_state): Delete.
	(push_file_scope, pop_file_scope): New stubs.
	* parser.c (c_parse_file): Call sorry() here if called more than once.

testsuite:
	* gcc.dg/Wold-style-definition-1.c, gcc.dg/builtins-30.c
	* gcc.dg/unused-4.c, gcc.dg/noncompile/label-1.c
	* gcc.dg/noncompile/label-lineno-1.c, objc.dg/naming-1.m:
	Adjust error regexps.
	* gcc.dg/Wshadow-2.c, gcc.dg/noncompile/incomplete-3.c
	* gcc.dg/noncompile/undeclared-1.c: New test cases.
	* gcc.dg/decl-5.c, gcc.dg/redecl-1.c: Remove XFAIL.
	* gcc.dg/local1.c: Add explanatory comment.

        * optabs.c (expand_binop): When synthesizing double word rotates
        from single word shifts, use a new register target if the provided
        target is not a REG already.
